to force the passage of the Hellespont, as the fleet of Licinius, instead of seeking and destroying their feeble enemy, continued inactive in those narrow straits, where its superiority of numbers was of little use or advantage. Crispus, the emperor's eldest son, was intrusted with the execution of this daring enterprise, which he performed with so much courage and success, that he deserved the esteem, and most probably excited the jealousy, of his father. The engagement lasted two days; and in the evening of the first, the contending fleets, after a considerable and mutual loss, retired into their respective harbors of Europe and Asia. The second day, about noon, a strong south wind sprang up, which carried the vessels of Crispus against the enemy; and as the casual advantage was improved by his skilful intrepidity, he soon obtained a complete victory. A hundred and thirty vessels were destroyed, five thousand men were slain, and Amandus, the admiral of the Asiatic fleet, escaped with the utmost difficulty to the shores of Chalcedon. As soon as the Hellespont was open, a plentiful convoy of provisions flowed into the camp of Constantine, who had already advanced the operations of the siege. He constructed artificial mounds of earth of an equal height with the ramparts of Byzantium. The lofty towers which were erected on that foundation galled the besieged with large stones and darts from the military engines, and the battering rams had shaken the walls in several places. If Licinius persisted much longer in the defence, he exposed himself to be involved in the ruin of the place. Before he was surrounded, he prudently removed his person and treasures to Chalcedon in Asia; and as he was always desirous of associating companions to the hopes and dangers of his fortune, he now bestowed the title of Cæsar on Martinianus, who exercised one of the most important offices of the empire.

Such were still the resources, and such the abilities, of Licinius, that, after so many successive defeats, he collected in Bithynia a new army of fifty or sixty thousand men, while the activity of Constantine was employed in the siege of Byzantium. The vigilant emperor did not, however, neglect the last struggles of his antagonist. A considerable part of his victorious army was transported over the Bosphorus in small vessels, and the decisive engagement was fought soon after their landing on the heights of Chrysopolis, or, as it is now called, of Scutari. The troops of Licinius, though they were lately raised, ill armed, and worse disciplined, made head against their conquerors with fruitless but desperate valor, till a total defeat, and a slaughter of five and twenty thousand men, irretrievably determined the fate of their leader. He retired to Nicomedia, rather with the view of gaining some time for negotiation, than with the hope of any effectual defence. Constantia, his wife, and the sister of Constantine, interceded with her brother in favor of her husband, and obtained from his policy, rather than from his compassion, a solemn promise, confirmed by an oath, that after the sacrifice of Martinianus, and the resignation of the purple, Licinius himself should be permitted to pass the remainder of this life in peace and affluence. The behavior of Constantia, and her relation to the contending parties, naturally recalls the remembrance of that virtuous matron who was the sister of Augustus, and the wife of Antony. But the temper of mankind was altered, and it was no longer esteemed infamous for a Roman to survive his honor and independence. Licinius solicited and accepted the pardon of his offences, laid himself and his purple at the feet of his lord and master, was raised from the ground with insulting pity, was admitted the same day to the Imperial banquet, and soon afterwards was sent away to Thessalonica, which had been chosen for the place of his confinement. His confinement was soon terminated by death, and it is doubtful whether a tumult of the soldiers, or a decree of the senate, was suggested as the motive for his execution. According to the rules of tyranny, he was accused of forming a conspiracy, and of holding a treasonable correspondence with the barbarians; but as he was never convicted, either by his own conduct or by any legal evidence, we may perhaps be allowed, from his weakness, to presume his innocence. The memory of Licinius was branded with infamy, his statues were thrown down, and by a hasty edict, of such mischievous tendency that it was almost immediately corrected, all his laws, and all the judicial proceedings of his reign, were at once abolished. By this victory of Constantine, the Roman world was again united under the authority of one emperor, thirty-seven years after Diocletian had divided his power and provinces with his associate Maximian.

The successive steps of the elevation of Constantine, from his first assuming the purple at York, to the resignation of Licinius, at Nicomedia, have been related with some minuteness and precision, not only as the events are in themselves both interesting and important, but still more, as they contributed to the decline of the empire by the expense of blood and treasure, and by the perpetual increase, as well of
